Creates a new phy_fixup and adds it to the list
int phy_register_fixup(const char * bus_id, u32 phy_uid, u32 phy_uid_mask, int (*run) (struct phy_device *));
bus_id
A string which matches phydev->dev.bus_id (or PHY_ANY_ID)
phy_uid
Used to match against phydev->phy_id (the UID of the PHY) It can also be PHY_ANY_UID
phy_uid_mask
Applied to phydev->phy_id and fixup->phy_uid before comparison
run
